Many people believe that a new habit becomes automatic after only twenty-one days, but researchers who ①examined real behavior found a different number. This project, ②called the 66-day habit formation study, tracked volunteers who tried to adopt a new daily habit, like drinking water with lunch. Researchers measured how automatic each action felt over time and found that habits ③needing an average of sixty-six days to become effortless. Yet the actual time varied widely, ranging from about eighteen days for simple habits to over two hundred days for ④difficult ones. This wide range explains why the popular twenty-one-day claim, though easy ⑤to remember, rarely matches real experience.

When Daniel was a child, he dreamed of becoming an astronaut, yet he assumed such careers ①belonged only to a handful of government scientists. By the time he entered university, however, the space industry had changed dramatically, as private companies began ②launching satellites and building reusable rockets. Daniel studied aerospace engineering, ③drawing to the idea that space exploration was no longer limited to a few national agencies. During an internship, he helped design a small satellite ④intended to monitor crop health from orbit. He realized that the space industry now needed not only pilots and engineers but also data analysts and technicians ⑤familiar with international space regulations.

Many students assume that perfectionists work harder than everyone else, but psychologists describe a puzzling pattern ①called the perfectionism-procrastination cycle. This term describes how an intense fear of imperfect work ②cause people to delay starting a task rather than begin it. Because perfectionists set impossibly high standards, they often feel anxious before they even begin, and the task feels ③overwhelming. They then postpone the work to avoid ④facing their own unrealistic expectations, even though delay only increases their stress later. For example, a student writing a research paper might spend hours reorganizing notes instead of composing a single sentence that ⑤feels good enough.

As governments and companies work to address climate change, a new category of employment known as green jobs has ①expanded rapidly. Unlike many traditional industrial jobs, green jobs often require workers to combine technical training with an understanding of environmental science. Countries that have invested heavily in renewable energy have seen employment in this sector grow far ②faster than in the economy overall. Young workers, in particular, are drawn to green careers because they offer a sense of purpose alongside financial ③stability. Critics point out that transitioning workers from fossil fuel industries to green jobs can be surprisingly ④easy, since the required skills can differ significantly. Governments are therefore introducing training programs designed to help such workers shift ⑤smoothly into renewable energy careers.

Time blocking is a time-management technique in which a person divides the day into fixed blocks. ___________. Instead of relying on a loose to-do list, the person decides exactly when each task will start and end. This approach lowers the mental effort of deciding what to do next, since the schedule already provides the answer. It also limits multitasking, because each block is reserved for only one activity at a time. For instance, a student may block ninety minutes for math practice, leaving no room for messages or web browsing. Another student may reserve an evening block solely for vocabulary review, treating that time like a fixed appointment. Because each block has a clear boundary, unfinished work is less likely to quietly spread into the next task. Many people who adopt time blocking feel more organized throughout the day.

Many teenagers check their social media accounts dozens of times a day, worried that they might miss something important happening among their friends. This anxiety, known as FOMO, or the fear of missing out, arises when people believe that others are enjoying experiences from which they themselves are excluded. For example, a student scrolling through photos of a party she was not invited to may suddenly feel a wave of loneliness and regret, even though the event has already ended. Constantly refreshing feeds to avoid missing such updates, however, makes it difficult to concentrate on schoolwork or conversations happening in the present moment. Moreover, this endless comparison with curated highlights of other people's lives tends to deepen feelings of anxiety rather than relieve them. Therefore, students should learn to ___________.

Online advertising has become increasingly personalized as algorithms analyze user behavior in real time. (A) Critics, however, warn that this precision can be used to exploit psychological weaknesses rather than genuinely help consumers. (B) Supporters claim that this precision benefits users by reducing the number of irrelevant advertisements they encounter. (C) Given these opposing views, many experts call for greater transparency about how such algorithms actually operate.

Yet the number displayed each morning is only as good as the estimate behind it. Wearable devices that track sleep have become enormously popular, promising a detailed breakdown of light, deep, and REM sleep each night. ( ① ) These gadgets typically rely on movement sensors and heart rate monitors to estimate sleep stages, since directly measuring brain activity would require equipment found only in a sleep laboratory. ( ② ) This indirect approach, however, introduces significant uncertainty. ( ③ ) Independent studies comparing wearable data with polysomnography, the gold-standard method used in clinical sleep labs, have found that consumer devices are reasonably accurate at distinguishing sleep from wakefulness but considerably less reliable at identifying specific sleep stages. ( ④ ) Some trackers overestimate deep sleep, while others underestimate the amount of time spent in REM sleep, and the margin of error can vary widely between brands. ( ⑤ ) Despite these limitations, many users have come to treat the nightly score generated by their device as an objective medical verdict, sometimes experiencing anxiety when the number falls below what they expect, a phenomenon researchers have begun calling orthosomnia.

주어진 문장: In other words, working longer hours does not necessarily lead to better results if that time is spent in a low-energy state. For decades, productivity advice has focused almost entirely on managing time efficiently, yet many experts now argue this approach overlooks something important. ( ① ) This alternative approach, known as energy management, suggests that controlling personal energy matters more than controlling the clock. ( ② ) Unlike time, which flows at a constant rate, human energy naturally rises and falls in cycles shaped by sleep, food, and mental fatigue. ( ③ ) A person who tackles difficult tasks during a low-energy period, for instance, may need two hours to finish what takes thirty minutes at peak energy. ( ④ ) Similarly, someone who forces themselves to keep working without rest often produces careless mistakes that require additional time to correct later. ( ⑤ ) Advocates of energy management recommend identifying one's peak hours and reserving them for demanding work, while saving low-energy periods for routine tasks.

주어진 문장: This constant tracking allows algorithms to build a detailed profile of each user's interests over time. Internet activist Eli Pariser introduced the term filter bubble to describe a phenomenon created by online algorithms. Social media platforms and search engines constantly track which links users click and how long they linger on certain posts. ( ① ) Based on this data, algorithms predict what each individual is most likely to enjoy and quietly prioritize similar content in future results. ( ② ) As a result, two people who type the same search query can receive strikingly different results, each tailored to personal history. ( ③ ) This automatic filtering happens silently, without users ever deciding to limit what they see. ( ④ ) Consequently, many people gradually lose access to viewpoints that challenge their existing beliefs, even though they never intended to avoid them. ( ⑤ ) Pariser warned that this invisible curation could weaken democratic debate by narrowing public discussion. Therefore, some experts argue that platforms should reveal how content is filtered, letting users knowingly escape their own bubbles.
